Call ResourceReady callback even image loading failed.

Call ResourceReady callback even image loading failed.

image-visual and svg-visual and npatch-visual call ResourceReady callback even
they fail to load image.

But when animated image load faild, it doesn't call ResourceReady.

This patch make both image-used visuals call ResourceReady callback
even if load state is failed.
